Errors when running puppeteer with docker

What are you trying to achieve?

I’m trying to run tests in Puppeteer in Docker. May just need to use more docker run flags or change something in the codeceptjs.json.

What do you get instead?

Here is the repo with my setup for reproducing the error.

From within that repo I run

docker run --net=host -v /Code/codecept-test:/tests codeception/codeceptjs

Which uses the codeception/codeceptjs docker image with ID 5bbce4c27fdb

and I get the following error

CodeceptJS directory has been found.
CodeceptJS v1.1.7
Using test root "/tests"

Details

From within the docker image I pulled the following

• CodeceptJS version: v1.1.7
• NodeJS Version: v8.9.1
• Operating System: uname -a provides Linux linuxkit-025000000001 4.9.75-linuxkit-aufs #1 SMP Tue Jan 9 10:58:17 UTC 2018 x86_64 GNU/Linux
• Puppeteer version: whatever is install in the docker image

I updated the helper section of my codecept config to pass the --no-sandbox arg and it seemed to work. What does this do and why is it required?

"helpers": {
    "Puppeteer": {
      "chrome":{
        "args": ["--no-sandbox"]
      }
    }
  },

Using the node:14 helped me to fix these problems.
